Knowledge-based search tactics are discussed in terms of their role in the functioning of a semantically-based search system for bibliographic information retrieval. This prototype system, EP-X, actively assists users in defining or refining their ...

AIR represents a connectionist approach to the task of information retrieval. The system uses relevance feedback from its users to change its representation of authors, index terms and documents so that, over time, AIR improves at its task. The result ...

This paper demonstrates how a neural network may be constructed, together with learning algorithms and modes of operation, that will provide retrieval effectiveness similar to that of the probabilistic indexing and retrieval model based on single terms ...

In conventional Boolean retrieval systems, users have difficulty controlling the amount of output obtained from a given query. This paper describes the design of a user interface which permits gradual enlargement or refinement of the user's query by ...

This paper describes the design of the information retrieval facilities of an integrated information system called EUROMATH. EUROMATH is an example of a Knowledge Worker Support System: it has been designed specifically to support mathematicians in ...

We show that any approach to develop optimum retrieval functions is based on two kinds of assumptions: first, a certain form of representation for documents and requests, and second, additional simplifying assumptions that predefine the type of the ...

'Probability is expectation founded upon partial knowledge.' (Boole, 1854)

Information retrieval based on stored program electronic computers has been an active area of research since the time these machines were invented. It is therefore somewhat ...

In this paper we present a parallel document ranking algorithm suitable for use on databases of 1-1000 GB, resident on primary or secondary storage. The algorithm is based on inverted indexes, and has two advantages over a previously published parallel ...

In this paper we propose a full text search system based on optics. The storage and processing of the textual data are performed by an optical back-end system to an electronic computer. In this way we can take advantage of the speed and parallelism of ...

Wide area networks provide a variety of information sources which can be exploited only by appropriate information retrieval techniques such as repeated automatic query of remote databases and bulletin boards. Distinctive features of the content and ...

This study summarizes various linguistic approaches proposed for document analysis in information retrieval environments. Included are standard syntactic methods to generate complex content identifiers, and the use of semantic know-how obtained from ...

A large and important class of optical disc technology are CLV format discs such as CD ROM and WORM. In this paper, we examine the issues related to the implementation and performance of several different file organizations on CLV format optical discs ...

We introduce a family of simple and fast algorithms for solving the classical string matching problem, string matching with don't care symbols and complement symbols, and multiple patterns. In addition we solve the same problems allowing up to k ...

In order to improve the two-level signature file method designed by Sacks-Davis et al. [20], we propose new multikey access methods based on term discrimination and signature clustering. By term discrimination, we create separate, efficient access ...

This paper focuses on the RIME system aimed to the indexing of medical reports in a multimedia environment. This particular application is viewed as representative of a large set of still unanswered needs of large communities of users: domain experts ...

In contrast to other kinds of libraries, software libraries need to be conceptually organized. When looking for a component, the main concern of users is the functionality of the desired component; implementation details are secondary. Software reuse ...

This paper reports on one of the findings of a larger case study that attempts to describe how people organize documents in their own offices. In that study, several dimensions along which people make classificatory decisions were identified. Of these, ...

Hypertext offers users a simple, flexible way to navigate through electronic information systems but at the potential risk of becoming lost in the network of interconnected pieces of information. A study was conducted on information retrieval using a ...

In organized health care, primary care is the first level. It is characterized by the wide span of health problems managed as well as remote location from traditional medical information and knowledge sources. The LIMEDS project has formulated the ...

This paper describes a system for formally representing spatial relationships between videodisc image states called settings. A number of setting relations are defined, these being based on the manipulations of the camera typically used in the ...

This paper documents research toward building a complete lexicon containing all the words found in general newspaper text. It is intended to provide the reader with an understanding of the inherent limitations of existing vocabulary collection methods ...

Software reuse is widely believed to be the most promising technology for improving software quality and productivity. There are many technical and non-technical problems to be solved, however, before widespread reuse of software lifecycle objects ...
